Hey people, was there a patch in the last couple months, or some new feature added in Dragonborn DLC (I just got this recently) whereby alchemy ingredients that aren't available for purchase from NPCs suddenly are now?

Started a new legendary game, went straight to leveling Alchemy from scratch, and all stocks were normal as they always have been. Then all of a sudden Nurelion is selling Bear Claws, Large and Small Antlers, Blue and Orange Dartwings, even Pearls. WTF?

Not using unofficial patch or any mods at all, so no clue what's going on here.

Hmmm, ok I actually wondered if that might be the thing. I never bothered with Speech perks, but now that there's legendary skills, I figured, might as well. Happened just after I took Merchant perk, so that makes sense I suppose.
